About Greenplum
The Greenplum Database builds on the foundations of the open-source database PostgreSQL. It primarily functions as a data warehouse and utilizes a shared-nothing, massively parallel processing (MPP) architecture. In this architecture, data is partitioned across multiple segment servers, and each segment owns and manages a distinct portion of the overall data; there is no disk-level sharing nor data contention among segments.

Unlike PostgreSQL, the Greenplum database does not support the binary option of the copy command
